Can Bus Fiber Optic Converter

2 Channel CAN BUS Fiber Optic Converter(No Cascading)

HFD-FO-CAN DIN Rail 2 Channel CAN Fiber optic Converter

Transmission rate:

The HFD-FO-CAN support all the transmission speeds (transmission rates):0-1Mbps.The converter can support 2 channels of CAN data input.The transmission rate is set automatically as soon as the canbus HFD-FO-CAN receives a frame. The setting or adjustment is dependent on the transmission rate. Depending on the HFD-FO-CAN Settings in automatical mode,

Segment monitoring at the optical line:

Each receiver monitors the optical line port connected to it for recive framesand status. If faulty frames are received by the receiver, or no single for longer than the maximum permitted time, forwarding of the received signals is blocked until the port status is ok,frames can be received again correctly.

Network Topologies:

The following network topologies can be realized with the HFD-FO-CAN:

  • Point-to-point topologies
  • Multi-drop Bus

Fiber Mode: Single mode or Multi Mode

Product Feature:

Buffer function:The HFD-FO-CAN can protect the data from being lost. Anti-stream: 1000 frames.

No cascading: The HFD-FO-CAN has no cascading,no frame loss when data is at high rate or long distance transmission.

Reliablity: Compared with other brands,the HFD-FO-CAN can help build up more stable and secure networks.

Dual 2 Channels of CAN BUS input: The converter can be connected to 2 CAN BUS devices simultaneously
